摘要： An optical position-measuring device includes a scanning bar extending in a first or second direction, and a scale extending in the other direction. The scale is offset by a scanning distance from the scanning bar in a third direction perpendicular to the first and second directions. The device has a light source whose light penetrates the scanning bar at an intersection point of the scanning bar and scale to fall on the scale and arrive back at the scanning bar. At a detector, the light is split by diffraction into different partial beams at optically effective structures of the scanning bar and scale and combined again. A periodic signal is obtained in the detector in response to: a shift between the scanning bar and scale in the first direction due to interference of combined partial beams, and a change in the scanning distance between the scanning bar and scale.

摘要： An optical position-measuring device includes a measuring standard and a scanning unit. The measuring standard includes an incremental graduation and at least one reference marking at a reference position. The reference marking has two reference-marking subfields disposed in mirror symmetry relative to a reference-marking axis of symmetry, each of the subfields including a grating structure having a locally changeable graduation period. The scanning unit includes a divergently emitting light source, one or more gratings, and a reference-signal detector system. The reference-signal detector system has at least four detector arrays formed and positioned such that, from the scanning of the reference marking via the reference-signal detector system, first and second pairs of partial reference signals result, in each case having a signal pattern in phase opposition. The first pair of partial reference signals is offset by an offset amount relative to the second pair of partial reference signals.

摘要： The present invention relates to a sun collector comprising a flat absorber body (1) on or in which one or more absorber channels (17) for the flow of a heat transfer medium are configured. In areas which are not occupied by the one or more absorber channels (17), the absorber body (1) of the present sun collector has penetrable openings (4, 10, 13) for sunlight to pass through. The sun collector therefore provides the double function of a sun collector with a partially transparent sun protection device.

摘要： An optical position-measuring device for detecting the position of two objects movable relative to each other in at least one measuring direction includes a measuring standard which is joined to one of the two objects and possesses an incremental graduation extending in the measuring direction, as well as at least one reference marking at a reference position. The reference marking includes two reference-marking subfields disposed in mirror symmetry with respect to a reference-marking axis of symmetry, each of the subfields being made up of a structure extending in the measuring direction and having a locally changeable graduation period. In addition, the position-measuring device has a scanning unit which is joined to the other of the two objects and to which a scanning device is assigned that is used to generate at least one reference signal at the reference position. The scanning device includes at least one light source emitting divergently in the direction of the measuring standard, as well as a detector system having elements which are disposed along the measuring direction such that, starting from a central detector-system axis of symmetry in the measuring direction, the center-to-center distances between adjacent elements in the same direction change like the graduation periods of the structures in the reference-marking subfields starting from the reference-marking axis of symmetry.
